Setting Input Resistance on the PXI-4071

[Jeffrey_Zola]

The specifications for the PXI-4071 DMM indicate that the input resistance can be chosen as either 10 MOhm or 10 GOhm for the 100 mV, 1 V, and 10 V ranges. I see where this can be input on the instrument soft panel, but I have been unable to locate how to configure the input resistance when using the DMM in a VI. Suggestions?

Thanks!

You need to use a property node.

Ah.  Looked at the Property Node, but didn't go deep enough. Nor could I find it in the help files or any of the other online documents.

Thanks!

One other somewhat important detail I found necessary: You must use the "Change All To Write" option on the menu that comes up by right-clicking on the Property Node. Otherwise, the DVM remains with 10MOhm impedance.

Just thought I'd add this for those who search for this thread later on!

Hey Jeff,

That is correct.  Otherwise, you're simply reading the input resistance, which by default is 10MΩ.  Let us know if you have any other questions!
